Research Description
Dr. Han is an associate professor with the Department of Emergency Medicine at Vanderbilt University. He completed his emergency medicine residency at the University of Cincinnati and also served as chief resident. He completed a research fellowship and obtained a Masters in Clinical Epidemiology. In addition to his clinical responsibilities in the emergency department, Dr. Han has been very active in patient oriented research. He has over 60 peer-reviewed publications, book chapters, and reviews in the areas of geriatric medicine, cardiology, and emergency department overcrowding. He is the recipient of the Vanderbilt Physician Scientist Development Grant and Emergency Medicine Foundation Career Development Award and has served as co-investigator on several NIH grants. Dr. Han was most recently funded by a National Institute on Aging K23 award which validated several brief delirium assessments for the emergency department setting and investigated how delirium in the ED affects long-term outcomes.
